The firings took place in September, and were made public Wednesday in Frederick’s statement.

According to the statement, some university employees received two kinds of benefits when they were only supposed to receive one. One kind of benefit is tuition remission, which waives tuition costs for employees who are enrolled in university classes. The other benefit was a university grant. The two benefits together added up to more than the cost of attendance, which resulted in the employees receiving improper refunds.

Frederick said he was first made aware of the problem in December, 2016. He later brought in an outside auditor to supplement the school’s internal investigation.

Howard completed its internal investigation of “individual employee actions” in September, 2017, and said it would refer any actions for “criminal prosecution” when appropriate. The employees were not identified.

The University is still working with outside experts to determine the total amount of misappropriated money during the nine-year span.

The statement also lists a series of new policies and procedures as a direct result of the investigation’s findings, including the hiring of a new chief compliance officer.

The announcement comes less than 24 hours after an anonymous post published on Medium alleged financial abuses at the University. NBC News was not able to independently verify the specific allegations made in the original Medium post.

The post was removed from Medium Wednesday afternoon.

Howard University officials tell NBC News the president’s statement Wednesday was not prompted by the Medium post.

In a radio interview with HBCU Digest, Frederick said he was very “concerned” about the results of the investigation getting out because criminal charges against individuals involved are still a “possibility.”

The revelations of financial abuses comes at a particularly challenging time for the prominent HBCU and its president.

Sunday night, HUResist, a student-led activist group at Howard, posted a list of nine demands ranging from better university housing accommodations to greater administration accountability. The group also called for Frederick’s “immediate resignation.”

Last year, faculty leaders voted “no confidence” in Frederick — though the vote’s legitimacy has been questioned. In addition to voicing their concerns on the availability of university housing, Howard students have been critical of Frederick’s visit with the Trump administration and his handling of certain student matters.

School officials tell NBC News the University plans to “exercise all options to recoup the funds” and that any money that is taken away from students is “unacceptable.”
